I was looking for a good quality ring holder for my Samsung S8. I was thrilled to read it was a fidget spinner also! It attached to my phone easily and it's very sturdy!
It also can be used to stand your phone on a table to watch videos and as I fidget alot and like to be playing with something I found the fidget spinner to be very useful to me. It's very pretty and sylish and I'd definately recccommend it!
